Abstract

The invention discloses an automatic bolt tightening device. The automatic bolt tightening device is characterized in comprising a rack, a sliding assembly capable of moving up and down is arranged on the rack, a clamping assembly and a tightening assembly capable of moving up and down are arranged on the sliding assembly, a conveying assembly and a lifting assembly are fixedly installed at the bottom of the rack, a workpiece table which can move horizontally and is suitable for placing a to-be-tightened shaft string is arranged on the conveying assembly, the lifting assembly is suitable for driving the workpiece table to move up and down, a control system is fixedly installed on the rack, and the sliding assembly, the clamping assembly, the tightening assembly, the conveying assembly and the lifting assembly are all electrically connected to the control system. According to the automatic bolt tightening device, the shaft string end bolt of a gear speed change mechanism can be automatically tightened, tightening data are more accurate, the manual operation intensity is reduced, the production takt is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile gearboxes, in particular to an automatic bolt tightening device. Background technique [0002] The gearbox is a very important part of the vehicle. It can change the transmission ratio through different gear pairs meshing, so as to expand the driving wheel torque and speed. With the development of modern technology, the gearbox has also been upgraded, from the original manual gearbox to the current automatic gearbox. At present, the more common automatic transmissions mainly include hydraulic automatic transmissions, mechanical stepless automatic transmissions, electronically controlled mechanical automatic transmissions and dual-clutch automatic transmissions. Among them, the dual-clutch transmission is different from the general automatic transmission system. It is both a manual transmission and an automatic transmission. In addition to the flexibility of a manual transmission and the comfor...
